Trimble technology has provided the autonomous controls for a Dynapac soil compactor working on a jobsite in Canada. This is one of the industry’s first public tests of a fully autonomous compactor on a live construction site, rather than under test at specially prepared areas.

The job is for the construction of an earth covered dam and the Dynapac compactor was used alongside conventional machines guided by operators to carry out the work. Trimble technology used in all of the soil compactors ensuring they worked as a team, covering the entire area efficiently.

The Trimble Earthworks Grade Control Platform for Autonomous Compactors was used to guide the Dynapac CA 5000 soil compactor. The project is for the Site C Clean Energy Project on the Peace River in northeast British Columbia. 

For some of the time, an operator did sit in the machine to oversee its working while the compactor was under autonomous control. At certain times the machine was used without a person in the cab when handling work close to an edge that would have posed risks for an operator. To optimise safety, the machine operated in geofenced areas on the site.

According to Trimble the fully autonomous machine completed 37 hours of real compaction work, operating alongside a mixed fleet of compactors, the rest of which were running the Trimble CCS900 Compaction Control System. Data from all machines – both with and without an operator – was delivered using Trimble WorksOS Software, which is being used as the system of record for all compaction data on the jobsite.

“The Site C project was the perfect place to begin live testing of the fully autonomous soil compactor because of the cost and safety benefits autonomy will bring to large infrastructure projects like this in the future, and because of the willingness of the project owner and contractor to use new technology on their jobsite,” said Cameron Clark, earthmoving industry director for Trimble’s civil infrastructure solutions. “We are pleased that this initial testing reinforces our philosophy that autonomous technology will play an important role in delivering a cheaper, faster, safer and greener future for the construction industry.”

    Effective compaction control is one of a series of technical innovations boosting performance efficiency – Mike Woof writes. Maximising compaction efficiency can be a major cost factor on construction projects. Both for soil and asphalt compaction sectors, the risk from leaving an area under or over-compacted is substantial.
